Total Value doubling on the report

Hi,

We have a report that is built on Opportunity Team subject area. I have Opportunity Total Value column in there and couple of columns that have calculations on it based off of team members and split values. The issue is that when we do a report total is doubles up the opportunity total value where there is a split. The opportunity team report is doubling the value for Total Opportunity Value in report when we do a grand total. Is there a way to fix it?

Thanks,

Mo
